Abstract
The invention relates to a method for calibrating a multiphase, in particular three-phase, inverter () having a respective switching element (T, T, T) on the high-voltage side and a respective switching element (T, T, T) on the low-voltage side for each of the phases thereof as well as a respective current sensor for at least some of the phases (I, II, III). The following steps are proposed: (f) switching off all switching elements (T-T), (g) switching on a switching element (T) on the high-voltage side for a first phase (I) and a switching element (T) on the low-voltage side for a second phase (II), (h) measuring the currents flowing through the first phase (I) and the second phase (II), (i) forming an average value from the measured currents, and (j) calibrating the inverter () on the basis of the formed average value. The invention also relates to an apparatus, a computer program and a computer program product.
